This is a colored picture from ~Invader-Rainer so all original line art credit goes to them. Coloring and shading credit goes to me!

I just love how this looks, like it came right of the show! I wonder why we never see Dib's nightmare version of Zim in the Halloween Spectacular of Spooky Doom, maybe because Zim is already a nightmare in his own right.
